```
open fun runTestOnUiThread(r: Runnable!): Unit
```

**Deprecated:** *Deprecated in Java.*

Helper for running portions of a test on the UI thread. Note, in most cases it is simpler to annotate the test method with[android.test.UiThreadTest](https://developer.android.com/reference/kotlin/android/test/UiThreadTest), which will run the entire test method on the UI thread. Use this method if you need to switch in and out of the UI thread to perform your test.

```
open fun sendKeys(vararg keys: Int): Unit
```

**Deprecated:** *Deprecated in Java.*

Sends a series of key events through instrumentation and waits for idle. For instance: sendKeys(KEYCODE_DPAD_LEFT, KEYCODE_DPAD_CENTER).

|                                                                 Parameters                                                                  ||

```
open fun sendKeys(keysSequence: String!): Unit
```

**Deprecated:** *Deprecated in Java.*

Sends a series of key events through instrumentation and waits for idle. The sequence of keys is a string containing the key names as specified in KeyEvent, without the KEYCODE_ prefix. For instance: sendKeys("DPAD_LEFT A B C DPAD_CENTER"). Each key can be repeated by using the N\* prefix. For instance, to send two KEYCODE_DPAD_LEFT, use the following: sendKeys("2\*DPAD_LEFT").

```
open fun sendRepeatedKeys(vararg keys: Int): Unit
```

**Deprecated:** *Deprecated in Java.*

Sends a series of key events through instrumentation and waits for idle. Each key code must be preceded by the number of times the key code must be sent. For instance: sendRepeatedKeys(1, KEYCODE_DPAD_CENTER, 2, KEYCODE_DPAD_LEFT).

|                                                                       Parameters                                                                        ||

```
protected open fun runTest(): Unit
```

**Deprecated:** *Deprecated in Java.*

Runs the current unit test. If the unit test is annotated with[android.test.UiThreadTest](https://developer.android.com/reference/kotlin/android/test/UiThreadTest), the test is run on the UI thread.  

### tearDown

```
protected open fun tearDown(): Unit
```

**Deprecated:** *Deprecated in Java.*

Make sure all resources are cleaned up and garbage collected before moving on to the next test. Subclasses that override this method should make sure they call super.tearDown() at the end of the overriding method.
